Mutations often don't effect the organism because they occur in the recessive gene. That means the dominant gene will cover up the effect of the mutation and it won't be expressed.
Meiosis only occurs in sex cells. It creates four daughter cells. Mitosis can occur in any cell and creates two daughter cells.
Two pros of genetic engineering is that it can select the best traits. It also can prevent bad traits. Two cons of genetic engineering is that it decreases the amount of diversity in organisms. It also may have negative side effects that are unknown.
<u>Answer:</u>
This very long molecule of DNA is called chromosome.
<u>Explanation:</u>
- Chromosome is a 'DNA molecule' that contains part or all of the genetic material of an organism.
- The 'three-dimensional genome structure' of chromosome plays a vital role in 'transcriptional regulation'.
- Prokaryotes have less sequence-based chromosome structure than eukaryotes.
- The recombination of chromosome during meiosis and successive reproduction plays a significant role in 'genetic diversity'.
- Chromosomes are normally visible under microscope during the metaphase of cell division. Chromosomes are the key elements of cell division.
Gravitational force, keeps the molecules in the atmosphere from moving into space. Gravity's influence is stronger near the earth's surface and weaker
